Dynamic virtualization technique for multicore processor system

Abstract

Disclosed is a method of allocating OS resources in a multicore processor system, including: setting a common operating system (OS) layer serving to process a common resource; setting a partitioned OS layer allocating one or more partitioned OSs to each of multiple cores; and reallocating the partitioned OSs allocated to the multiple cores in the partitioned OS layer on the basis of system resources required to drive each OS.

1 . A method of allocating OS resources in a multicore processor system, comprising:
 setting a common operating system (OS) layer serving to process a common resource;   setting a partitioned OS layer allocating one or more partitioned OSs to each of multiple cores; and   reallocating the partitioned OSs allocated to the multiple cores in the partitioned OS layer on the basis of system resources required to drive each OS.   
     
     
         2 . The method of  claim 1 , wherein the common OS layer performs at least one function of global memory management and common device management. 
     
     
         3 . The method of  claim 1 , wherein the partitioned OS layer independently manages resources of a local memory. 
     
     
         4 . The method of  claim 1 , wherein multiple OSs are partitioned and allocated to one core. 
     
     
         5 . The method of  claim 1 , wherein resources of the multiple cores are dynamically reallocated by reallocation of the partitioned OS in the partitioned OS layer.
